Course Outline
Cluster Setup
- Implement Network security policies to limit cluster-level access
- Leverage the CIS benchmark to assess the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Secure node metadata and endpoints
- Limit the usage of and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Restrict access to the Kubernetes API
- Apply Role Based Access Controls to reduce exposure
- Handle service accounts with care, such as disabling defaults and minimizing permissions on newly created ones
- Keep Kubernetes up to date with frequent updates
System Hardening
- Reduce the host OS footprint to shrink the attack surface
- Minimize IAM roles
- Limit external access to the network
- Utilize kernel hardening tools like AppArmor and seccomp appropriately
Minimize Microservice Vulnerabilities
- Establish proper OS-level security domains using tools like PSP, OPA, and security contexts
- Manage kubernetes secrets effectively
- Employ container runtime sandboxes in multi-tenant environments (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption via mTLS
Supply Chain Security
- Reduce the base image footprint
- Safeguard the supply chain by whitelisting image registries and signing/validating images
- Perform static analysis on user workloads (e.g., kubernetes resources, docker files)
- Scan images for existing vulnerabilities
Monitoring, Logging and Runtime Security
- Conduct behavioral analytics of syscall processes and file activities at both host and container levels to identify malicious actions
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Track all phases of an attack, regardless of origin or propagation method
- Execute deep analytical investigations to identify malicious actors within the environment
- Guarantee container immutability during runtime
- Monitor access using Audit Logs
Requirements
- CKA (Certified Kubernetes Administrator) certification
Audience
- Kubernetes practitioners
